Geoffrey the Elder (died after 1085), a nephew of Robert Guiscard through one of his sisters, was the count of Conversano, Brindisi, and Nardò from 1068 to his death.
According to Goffredo Malaterra, Geoffrey conquered most of his lands (castra) with his own energy (sua strenuitate) and without the help of the Guiscard. Thus, when, in 1067, the Guiscard demanded homage for the castle of Montepeloso, Geoffrey refused. Robert brought him to heel in the subsequent war and Geoffrey did homage. Among the other lands Geoffrey had conquere from the Byzantines were Polignano and Monopoli.
Geoffrey joined his cousins Abelard and Herman and his brother Robert in the rebellion of 1079-1082, while the Guiscard was away fighting the Byzantine Empire in the Balkans. His brother died in July 1080 and Abelard a year later. While he was besieging Oria, a city on the Via Appia between Brindisi and Taranto, Robert returned at Otranto and began to march towards him. Geoffrey, though he had numerous troops, fled anyway.
By 1083, Geoffrey was reconciled to Robert Guiscard and accompanied him on his final Byzantine expedition. He last appears in 1085 and left three sons and a daughter
